Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for identifying and mitigating artifacts in projection data or reconstructed image data, comprising: generating at least one of projection data or reconstructed image data by a scanning device; displaying the at least one of projection data or reconstructed image data having visually observable artifacts generated by a scanning device, wherein the at least one of the projection data or the reconstructed image data corresponds to an imaging examination of an object or subject; identifying one or more sample images other than of the object or subject with known artifacts having artifacts similar to the visually observable artifacts in the at least one of the projection data or the reconstructed image data; obtaining data from at least one of the projection or reconstructed image data indicative of a characteristic of the at least one of the projection or reconstructed image data; filtering the identified one or more sample images other than of the object or subject with known artifacts having artifacts similar to the visually observable artifacts in the at least one of the projection data or the reconstructed image data to correspond to the data thereby identifying a subset of one or more sampled images; displaying, concurrently with the at least one of the projection data or the reconstructed image data having visually observable artifacts, the subset of the one or more sample images other than of the object or subject with known artifacts filtered to correspond to the data, and information related to mitigating the visually observable artifacts; and wherein the displaying, the identifying, the obtaining, the filtering, and the displaying concurrently are performed by a configured processor.
2. The method of claim 1 , wherein the scanning device uses at least one of computed tomography (CT), Positron-Emission Tomography (PET), Single-Photon-Emission Tomography (SPECT), or Magnetic Resonance Imaging (MRI) modalities.
3. The method of claim 1 , wherein the information includes information related to removing or reducing the visually observable artifacts from the at least one of the projection data or the reconstructed image data.
4. The method of claim 1 , wherein the information includes information related to mitigating an occurrence of the visually observable artifacts in projection data or reconstructed image data in connection with a subsequently performed imaging examination.
5. The method of claim 1 , wherein the sample images are displayed in at least one of an interactive graphical viewer.
6. The method of claim 5 , wherein the interactive graphical viewer allows for scrolling through the sample images.
7. The method of claim 1 , wherein the subset is filtered to correspond to the data by at least one of scanned body part, patient size, patient sex, imaging protocol, or presence of a contrast.
8. The method of claim 1 , wherein the data corresponds to anatomy represented in the at least one of the projection or reconstructed image data.
9. The method of claim 1 , further comprising: determining relevance scores for the sample images in the subset; and sorting a display order of the sample images in the subset based on the relevance scores.
10. The method of claim 1 , wherein the information includes at least one of textual, graphical or audible information.
11. The method of claim 1 , wherein the information recommends processing the projection data and reconstructing the processed projection data to generate second reconstructed image data.
12. The method of claim 1 , wherein the information recommends repeating the imaging examination under a different set of operating conditions.
13. A computing system for identifying and mitigating artifacts in projection data or reconstructed image data, comprising: a scanning device configured to generate the at least one of projection data or reconstructed image data; computer readable storage medium, including: non-transitory application memory encoded with instructions for an image artifact identification application; and data memory encoded with the at least one of projection data or reconstructed image data utilized by the image artifact identification application and generated by the scanning device; and one or more processors configured to execute the instructions for the image artifact identification application, wherein the executing instructions: identify one or more sample images other than of an object or subject with known artifacts having artifacts similar to visually observable artifacts in the at least one of the projection data or the reconstructed image data, obtain data from the at least one of the projection or reconstructed image data indicative of a characteristic of the at least one of the projection or reconstructed image data; filter the identified one or more sample images which identifies only a subset of the one or more sample images with known artifacts that correspond to the data; and display an interactive graphical viewer with only the subset of the one or more sample images with the known artifacts concurrently with at least one of projection or image data from an imaging examination of the object or subject filtered to correspond to the data and each filtered sample image includes information related to mitigating the known artifacts.
14. The system of claim 13 , further including: the scanning device configured to generate the at least one of projection data or reconstructed image data using at least one of computed tomography (CT), Positron-Emission Tomography (PET), Single-Photon-Emission Tomography (SPECT), or Magnetic Resonance Imaging (MRI) modalities.
15. The system of claim 13 , wherein the information includes information related to removing or reducing a visually observable artifact from the at least one of the projection data or the reconstructed image data using previously acquired image data.
16. The system of claim 13 , wherein the information includes information related to mitigating an occurrence of a visually observable artifacts in projection data or reconstructed image data in a subsequently performed imaging examination.
17. The system of claim 13 , wherein the interactive graphical viewer allows for scrolling through the sample images.
18. The system of claim 13 , wherein the information includes audible information.
19. The system of claim 13 , wherein the sample images are evaluated before the imaging examination and used to obtain information related to avoiding artifacts with the imaging examination.
20. The system of claim 19 , wherein the information is obtained through at least one of a key word search of the sample images based on anatomy to be scanned or scrolling through a set of sample images corresponding to the anatomy to be scanned.
21. The system of claim 13 , wherein the sample images are utilized independent of the imaging examination to train a clinician to recognize certain artifacts in projection and/or image data.
22. The system of claim 13 , wherein the interactive graphical viewer allows for adding new sample images with known artifact for subsequent evaluation.
23. The system of claim 13 , wherein the information includes a recommended processing step to remove an artifact from the at least one of the projection data or the reconstructed image data, and the system automatically performs the recommended processing step.
24. A non-transitory computing readable storage medium encoded with computer readable instructions for identifying and mitigating artifacts in projection data or reconstructed image data, which, when executed by one or more processors of a computing system, cause the computer system to: identify sample images with known artifacts having artifacts similar to visually observable artifacts in at least one of projection data or reconstructed image data from an imaging examination generated using at least one of a computed tomography (CT), a Positron-Emission Tomography (PET), a Single-Photon-Emission Tomography (SPECT), or a Magnetic Resonance Imaging (MRI) modality, obtain data from the at least one of the projection or reconstructed image data indicative of a characteristic of the at least one of the projection or reconstructed image data, filter the identified sample images with known artifacts having artifacts similar to the visually observable artifacts in the at least one of projection data or reconstructed image data, and display an interactive graphical viewer displaying only a subset of the identified sample images with known artifacts filtered to correspond to the data concurrently with the at least one of projection or image data, wherein each filtered sample image includes information related to mitigating a corresponding artifact and each filtered sample image is of an object or subject different from the imaging examination.
